Phrygilus punensis
The Peruvian Sierra Finch (Phrygilus punensis) is a striking medium-sized passerine, typically measuring 14-16 cm in length and weighing between 25-30 grams. Males are particularly handsome, boasting a contrasting dark slate-gray head and back that sharply meets vibrant yellow underparts, sometimes with an olive wash on the flanks, and a white lower belly and undertail coverts, all complemented by a dark bill.

Exclusively inhabits high-altitude Andean grasslands (puna) and rocky slopes, thriving above the tree line in arid to semi-arid alpine environments, typically between 3,500 m and 5,000 m.
Mainly granivorous, feeding on small seeds from high-Andean grasses and herbaceous plants, supplemented with small insects and larvae, especially during the breeding season. It forages primarily by gleaning from the ground.
